Exposure Head and Image Forming Device

Abstract

An exposure head includes an imaging optical system arranged in a first direction, and first and second light emitting elements disposed in a second direction substantially perpendicular to the first direction that emit light beams to be imaged by the imaging optical system to form light-collected sections adjacent to each other in the first direction. A first wiring is electrically connected to and extended out from the first light emitting element to one side in the second direction. A second wiring is electrically connected to and extended out from the second light emitting element to the one side in the second direction.
